// Being the head of a clan doesn´t equal being a father figure.
Yes, Leo might take being the head of the clan now - which isn´t much different than being a leader. But Leo is not a father figure in my eyes. Splinter trained him to guide and lead his brother not to take over the role of a father.
You know weird this even is? Giving the father role to a SIXTEEN year old over his brothers who are the exactly same age.
Beside can you guys see Raph or Donnie seeing him as a father figure?
